← ScienceWhich consequence results when orbital hybridization mismatches within semiconductor nanocrystals?
A)Decreased quantum dot photoluminescence efficiency✓
B)Increased thermal conductivity throughout lattice
C)Enhanced electron-phonon scattering processes
D)Improved nanocrystal structural tensile strength
💡 Explanation
When orbital hybridization is mismatched, increased surface defects act as non-radiative recombination centers, because these defects quench excited state energy via non-radiative pathways rather than photon emission via the exciton recombination mechanism. Therefore, luminescence decreases rather than increases or changes in thermal/mechanical properties.
